Apple and Overstock top consistency ratings in October

Apple.com had the best consistency score for Internet Explorer testing among large retailers tested in October, says Compuware Gomez. Last month, the retailer had the most consistent Internet Explorer site loading time with a variation of 0.59 seconds. Overstock.com had the best Firefox consistency score at 0.74 seconds.

Dell.com (0.60 seconds) placed second in Internet Explorer tests. Overstock.com (0.66) came in third, followed by OfficeMax.com (0.88) and OfficeDepot.com (1.07).

In Firefox testing, Apple.com and OfficeMax.com tied in second place behind Overstock.com with a variation of 0.88 seconds. Dell.com was next (0.92) and OfficeDepot.com (1.13 seconds) was fifth.

The average Internet Explorer consistency score among the 21 retailers measured in August was 1.64 seconds. The same group of retailers produced an average Firefox score of 1.99 seconds.

The consistency ratings take into account differences in the speed of web page delivery across multiple visits.
